ALBERT PEARSON, OF WESTERN SPRINGS, ILLINOIS, ASSIGNOR T0 WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK APPARATUS FOR DRYING PARTS Application filed May 16,

This invention relates to an apparatus for drying parts and more particularly to an apparatus for drying parts subsequent to their being subjected to an electroplating process.

The principal object of this invention is to provide an apparatus for readily, efliciently, and expeditiously drying parts.

In accordance with one embodiment of the present invention, there is provided a plurality of transferring means for lowering articles into arinsing bath, removing the articles from the bath and moving them laterally away therefrom. A plurality of spiders are positioned so that a series of intermittent jets of air may be directed upon the articles as they emerge from the rinsing bath, the air supply being controlled by the transferring means whereby air under pressure may be supplied to the spiders when the articles begin their movement from the rinsing bath, and the air supply to the spiders may be cut off when the articles have moved past the spiders.

Other features and advantages of the invention will become apparent from the following detailed description of one embodi ment thereof, reference being had to the accompanying drawings, wherein Fig. 1 is a front elevational view of the invention;

' Fig. 2 is a plan view taken along the line 2-2 of Fig. 1; 1

Fig. 3 is a front elevational view of one of the spiders, a portion thereof being shown in section;

Fig. 4 is a top plan view of one of the spiders, and p Fig. 5 is a horizontal sectional view of the valve.

Referring now to the drawings wherein like reference numerals designate corresponding parts throughout the several views,

"it will be observed that a rinsing tank indicated generally at 10 has a rinsing fluid 11 therein, above the surface of which are disposed pairs of equally spaced spiders 1212. The spiders 12 are identical in construction, and consequently a description of one of the spiders is considered sufficient for a clear un- 1930. Serial No. 453,094.

derstanding of the invention. By viewing Figs. 3 and 4 it will be noted that the body portion 13 has a threaded aperture 14 arranged to receive a threaded end of an air pipe 15 so as to communicate with an aperture 16. A reduced portion 17 providing an annular shoulder 18 has, a. reduced threaded member 19 integral with the end thereof and circumferentially disposed equally spaced apertures 20 positioned substantially .at the center thereof in communication with the aperture 16.

A rotatable collar 21 is disposed concentric with the reduced portion 17 upon the shoulder 18 and is held against displacement by a nut 22 upon'the reduced threaded member. Disposed in the inner surface of the collar 21 is an annular recess 23 which communicates with diametrically opposed outlet openings 24 into which the inner ends of pipes 25 are threaded. The other ends of the pipes 25 have directing means, such as nozzles '26 and 27 secured thereto and provided with relatively large outlet openings 28 and 29 respectively, in general alignment with center lines of the pipes 25. 'Relatively small apertures 32 and 33 extend in opposite directions to the forward and rearward sides of their respective nozzles 26 and 27, for a purpose hereinafter described.

The spiders 12 (Figs. 1 and 2) are connected to a main air line 37 in which is. disposed valve 38 normally held closed by a spring 39 and adapted to be actuated by movement of a cam lever 40. The movement of the cam lever 40 is brought about by carrier-s41 which are moved to immerse articles .in and remove them from a rinsing bath or fluid 11 by cam controlled arms 42 and are moved away from the rinsing bath by an endless chain 43 which'is moved to the right. (Fig. 1) as indicated by the arrow. The arms 42 are slidable in rotating supports 44 and have theirengaging ends disposed in operative relation with continuous recess earns 45 so that the carriers may be moved upwardly, in the direction of the arrow, to remove the "articles from a treating tank indicated gencarriers 41 have horizontally extending sup porting arms 47 upon which are hooked carryingbars 48 having articles 49 to be treated secured thereto. The parts 49 (Fig. 1) are submerged in the bath 11 and are moved slowly to the position between the pairs of spiders 12 due to the relatively slow movement of the chain 43 upon which the carrier is disposed. The carrier is then moved upwardly so as to remove the parts 49 from the rinsing bath and is moved laterally and then downwardly so as toagain place the carrier upon the chain 43 outside the rinsing tank 10. As this carrier is moved laterally by the chain 43, it is moved into engagement with the cam lever 40, thus opening the valve 38 and allowing air under pressure to be directed to the spiders 12 prior to and during the movement of parts from the rinsing bath 11.

The cam control arms 42 and their actuating means are synchronized in their movement so that a carrier together with the parts being treated will be moved from the treating bath 46, at the same time a carrier together with the parts being rinsed are moved from the rinsing bath 11. Furthermore, the carrier 41 is disposed in engagement with the chain 43 simultaneously and as they are moved laterally the carrier adjacent the valve 38 engages the cam lever 40, thus actuating the valve prior to and during the lifting of the.carrier, immediately to the left thereof, from the rinsing tank.

When the valve 38 is open, and the air under pressure is directed to each of the spiders it will pass through the aperture 16, through the apertures 20 into the annular recess 23 where it will be directed through the pipes 25 to thenozzles 26 and 27. The greater part of the air under pressure will pass outwardly through the apertures 28 and 29 but a small amount of air will pass through the apertures 32 and 33, causing a rotation of the collar 21 and the members carried thereby, thus directing intermittent jets of air against the parts 49 simultaneously from both sides thereof to readily dry the parts as they are drawn from the bath. The speed of the rotation of the spiders may be varied by turning the nozzles 26 and 27 to-vary the positions of the apertures 32 and 33. With the apertures 32 and 33 positioned as shown in Figs. 3 and 4, the spiders will be rotated at a relatively fast rate of speed, but by rotating the nozzles 26 and 27 so as to move the apertures toward a vertical position the rotating speed of the spiders will be decreased. Therefore, with this construction, the spiders may be rotated at any desired speed.

Even though this embodiment of the invention shows an arrangement of the spiders in pairs so as to dry partsraised out of a rinsing bath, it is obvious that the spiders may be disposed in any desired positions rel- .ative to any desired type of rinsing means without departing from the spirit and scope ofthe invention.

What is claimed is:

1. In ,an apparatus for drying articles, a bath, a pluralit vof transferring members for moving artic es into and out of said bath, and means rendered effective by one of said transferring members for causing air under pressure to be directed toward the articles moved from said bath by another of said transferring members.

2. In an apparatus for drying articles, a bath, a plurality of transferring members for supporting articles and moving the articles into and out of said bath, and means actuated by one of said transferring members for directing air under pressure upon the articles carried by another of said transferring members while being removed from said bath, said means being rendered ineffective when the articles being dried have been moved beyond the path of air under pressure.

'3. In an'apparatus for drying articles, a rinsing bath, a plurality of spaced transferring members for carrying articles to be dried, means for moving said transferring members successively for lowering the articles into said bath, means for moving the transferring members successively for moving the articles out of said bath, air spraying members disposed at spaced positions above said bath, a. valve affording communication between said spraying members and an air supply, and means for imparting lateral movement to said transferring members whereby one of said transferring members may open said valve for allowing air under pressure to pass through said air spraying members and upon the articles carried by another transferring member while the articles are being removed from said bath.

4. In an apparatus for drying articles, a rinsing bath, a plurality of spaced transferring members for carrying articles to be dried, means for moving said transferring members successively for lowering the articles into said bath, means for moving the transferring member'successively for moving the articles out of said bath, air spraying members disposed at spaced positions above said bath, a valve afi'ording'communication between said spraying members and an air supply, and means for imparting lateral movement to said transferring members whereby one of said transferring members may open said valve for allowing air under pressure to pass through said air spraying members and upon the articles carried by another transferring member while the articles are being removed from said bath, said transferring member adjacent said valve being arranged to release said valve whereby said valve may be closed for cutting off the communication between said air directing means and the air supfily when the articles removed from said bat have passed bythe air directing means.

5. In an apparatus for drying articles, a treating bath, means for successively moving articles into and out of said bath, and means rendered effective upon the movement of an article to a predetermined position for causing air under pressure to be directed upon another article upon being removed from said bath.
